Oh, sorry. I forgot that LoU is only compatible with LoA. Where did you download the myros mod from and when? I think there may be an updated version at SiegeNetwork that does not require untanking the mod.

Also, this may offer a solution about online play and saving quests:
Ikkyo's Multiplayer Quest Save is a modification for Dungeon Siege(TM) by Gas
Powered Games, Inc.(TN).
The one thing that annoyed me about the multiplayer version of the Ehb map
was that the current states of the quests were not saved between game
sessions. With this modification, that annoyance no longer exists. Also,
starting with Beta 2, the Utraean Peninsula map is supported as well.
File is also available from SiegeNetwork.

*edit*
Additionally, there is a mod that I use that incorporates the MP quest saving feature as well as new items, and a adjustable camera (so you don't have to look down all the time in game). It is called Dungeon Siege Revived and you can find it at Herena Forge (free registration)
Herena Forge v2
DS: Revived: * SnowFox's playable goblin with support for all of Revived's features * Fixed singleplayer hireling bugs * Spellicon bar always shows the proper spells now * Spellicon bars for all eight characters in a party * Passive spell and potion ammo readout for all eight characters * Sanity checks for proper installation * Updated spellicon button graphics * Katar descriptions * Bow damage descriptions * New ranged skills ** Twin Strike ** Triple-shot ** Reaching Shot ** Greater Reaching Shot ** Penetrate * Prevent multiple ui_managers from spawning * HTML readme file ****NOTE: THIS IS NOT FOR DS:LOA****
Ok, I am out of suggestions, but can try to answer your questions about these mods or other DS stuff.
*edit* I just saw this:
Blast it! You did'nt tell me that I need the "LoA" expansion in order to play "LoU"!!! :-(
So much for that idea then!!!
Don't get discouraged or angry, I think there is a solution...
